Fan belts not lining up
#1
        I purchased the 3 belts for the engine and went to install them just to make sure they fit properly. Found the diagram and then discovered the pulleys don't line up. The rebuilt 302 has a ProStreet harmonic balancer on it, I can't compare the depth to the original as I never had one. If you look at the pictures you can see the gap if I install the belts and let them hang straight down. Is there a spacer that should go between the crank pulley and damper? AC, PS and alternator all located where they belong and line up except on lower pulley. Bottom photo shows the gap between the damper and pulley.

Both pictures you posted are the same.

Are you talking about front to rear alignment of the pulleys or not being able to tighten the belts? If you're talking about alignment we really need to see pictures taken from the side in line with the pulleys.

……….. And the correct orientation!

Also, most Ford engines I've dealt with that have AC have a double groove pulley on the water pump, yours looks like a single groove. How many grooves on the crank pulley?

Sorry for he double photos and missing pic. Ran out of time and couldn't correct it or he orientation. The crank pulley has 3 channels on it. Hopefully his pic will come in.

Did you read the directions for the damper?

I did but by the time I got around to reading and installing the damper in the new engine, the old one was long gone. Since it came with the new damper I never thought of removing the old one (and spacer) before turning in the core. I did check out some vendors to see if this was a common item and I found several different width crankshaft pulley spacers available. They have all different offsets to I just need to figure that out. This was in the one for 1" offset. 

"Replace the old or damaged crank pulley spacer on your 289, 302 or 351W engine with this high-quality 1" 4-Bolt Crank Pulley Spacer 1433 from March Performance!"
